Rear-Wheel Drive vs Front-Wheel Drive vs All-Wheel Drive

Top Gear © BBC 2000. "Old Top Gear", broadcast on 09 March 2000 [LOW VIDEO QUALITY] Vicky Butler-Henderson (Fifth Gear) tests and compares three different automotive drivetrains: rear-wheel drive (RWD), front-wheel drive (FWD) and all-wheel drive (AWD). NOTE: It must be noted that the Audi A4 quattro was a vehicle developed primarily as a front-wheel and not an all-wheel drive car, with most of its kinetic layout (weight distribution, suspension structure, relative wheel distribution, etc.) conceived for front-wheel propulsion. It has a traction torque bias towards the front wheels. Neither was it equipped with active limited-slip differentials (ie front- or rear axles or in the shaft in-between) to distribute torque/traction as per contingent wheel grip. By contrast other front-engined, all-wheel drive vehicles (ie Subaru Impreza WRX STi, Mitsubishi Lancer Evo) are conceived from the onset with permanent and symmetrical all-wheel drive systems and are often equipped with various arrays of slip differentials in the front- and rear axles and in the torque shaft, resulting in an altogether significantly different vehicle dynamic behaviour. It should also be mentioned that since the broadcast of this film, several traction systems have been developed, for both front and all-wheel drive vehicles, notably mechanical or electronic differentials for front-wheel drive cars eg those developed by Alfa Romeo, Ford, Citroën or Nissan. Finally, it should be noted that the criteria for <b>...</b>
